HIGH-PRESSURE STEAM COOKING VESSEL.

Application filed February 26, 1910. Serial No. 548,175.

To all whom it may concern:

Be it known that I, Runes L. PAGE, a citizen of the United States, residing at Puxic'o, in the county of Stoddard and State of Missouri; have invented a new and useful Improvement in High-Pressure Steam Cooking Vessels, of' which the following is a specification. f

This invention relates to certain new' and useful improvements in cooking ve'ssels, the object being to provide a cooking vessel which is so constructed that vegetables of all kinds can be readily cooked inhigh alti tudes, thereby overcoming the ydisadvantages of cookin vessels now in use, and at the same time f have provided a vessel in which the time required for cookin in all altitudes is much shorter than with t e time required with ordinary vessels. l

Another object of my invention is to provide a cooking vessel with an automatic valve whereby the steam will be allowed to escape after a certain amountof pressure has been obtainedwithin the vessel, so as to prevent the vessel from exploding.

.A still further object of my invent-ion is to ,provide means for adjusting the valve iu order to allow the steam to escape therefrom at any desired pressure which enables the vessel to he used in laboratories to demonstrate the effect that pressure has upon the boiling point of Water or other fluid.

Another object of-smy invention is to provide a cooking vessely which is exceedingly i simple and cheap 1n constructiom and one which is very strong and durable and in which the parts are so-mounted in respect to each other that all danger of the parts getting out of order is prevented.

lVith these objects in view,` the invention consists in the novel features of construetion, combination and arrangement of parts, hercinafterfully described and pointed outin the claim.

In the drawing forming a part of this specification: Figure l is a side elevation of my improved cooking vessel. F ig. 2 is a vertical section through the saine. Fig. is a horizontal section, and Fig. i is a detail view showing the manner of connecting the cover to the vessel. Fig. 5 is a detail vertical section.

In carrying out my improved invention I employ a vessel A, wliich-`may vbe, formed of any suitable material and is provided withan annular inwardly projecting depending flange A", 'at itsupper edge on which is ladapted to be seated the annular yinwardly `projecting depending iiange B', of a cover B, the lflanges being so' formed that an ex ceedingly tight joint is formed between the same. Extending outwardly from the opposite sides of the vessel'A are spaced apertured lugs C, in which are pivotally mounted blocks D which ,are Provlded with trans# verse threaded bores D,in whichare mounted thumbscrews adapted to lit in 'the slotted ends F', which are secured on' top of the cover at op# posite points, s o that after the screws have been forced in the slots tightening u on the same, the cover9 can'be drawn tight-ly down on the.vessel, so as to form a perfect steam tight joint between the iianges. By this construction when the screws'are loosened they can be swung outwardly so as to throw the same out of engagement with the plates in order to allow the cover to be readily raised. j

l'he cover B is provided with a central opening having an upwardly rejecting cylindrical portion Gr surrounding the saine provided with guidewvays Gr inwhich are adjustably mounted the depending arms H', of the substantially inverted Ushaped frame H which are locked in their adjusted positions within the respective `guide-ways by set-screws H2 vcarried by the guideways whereby the frame can he adjusted u and down for the purpose hereinafter ful y described.

Mounted within the upwardly projecting cylindrical portion of the cover isa cylindrical valve I which is provided with acentral upwardly projecting rod I extending through a central opening formed in the cross bar of the U-shaped, frame and said rod is surrounded by a coiled spring I2 for normally holding the valve down within the cylindrical portion of the cover. Thecylindrical valve is provided with an annular flange la at its ,up-per edgefor limiting the downward .movement of theL same within lthe casing, and it will be seen that b ad` justing the frame in respect to the cylindrispring bearing 'on the-valve can be adjusted, so as to regulate the valve in order that this sanie will o en at any desired pressure obtained within the vessel. The valve I is provided with a series of vopenings K which may be marked or graduated in any way,l so

of the respective plates 1i" yPatented Dee. 5, 1911.

ics cal. portion of the cover, tension of the as to indicate the pressure within the vessel, and these openings form outlets for the steam when the same is raised above the cylindrieal portion of the cover by the presA sure of the steam, so that the steam can readily escape in order to prevent the vessel from exploding. By adjusting the frame, so as to increase the compression of the spring, the valve will be held within the cylindrical portion of the cover until a greater pressure is obtained Within the vessel, and by raising the seme the valve will be allowed to move upwardly when the steam pressure within the vessel becomes greater than the pressure of the spring. For preventing the steam escaping out of the4 openings ot the valve from burning the hands of the user of the vessel, I provide the flange of the valve with a trough-shaped casing K which extends down over the openings, and is spaced therefrom to accommodate the cylindrical portion of the cover, and

it will be seen by this construction the steam will be carried downwardly.

What I claim is:

A device of the kind described comprising a cooking vessel, a detachable top adapted to be firmly secured thereto, a central cylindrical, upward extension carried by said cover, a cylindrical valve closed at the top and opening downwardly and snugly litting said extension, said valve having side openings arranged in vertical alinement, downwardly extending casings vcarried by the valve and covering said openings, said casings opening downwardly, an adjustable frame carried by the said extension, and a spring bearing respectively upon said frame and upon said valve.
